This was my gobbing off on another thread. I feel it deserves a wider audience "I just refuse to believe that it's impossible to rig a cheap system that would allow you to designate a target with a laser and then have the electronics tell the mortar tube when it's in the right position. Think about it - little plastic "rifle" with a laser pointer/range finder and GPS. Reason tells you that for any target in range of a mortar tube there must be a position for the tube that will result in the bomb striking. Point the "rifle" and paint the target. The GPS knows where the tube is, it now knows where the target is, cheap electronics tells the tube what position it needs, Number Two moves the loaded tube until it indicates it's bang on, and one second later it fires. Cost of 10lb of HE on target - couple of hundred quid. To mirror the range of the Javelin you would only need a thin aluminium low pressure, low velocity tube. The rest of the stuff wouldn't be dear either. But why have a cheap and simple solution when a complicated and expensive one will do Mr B. Wallis (I wish) Now am I missing something here. Action this day. I'm sure Maplin could knock the tube and electronics out for about Â£60, in time for the Xmas market.
